Chimpanzees are primates in the family Homo, belonging to the genus Chimpanzees. The body is bloated, with long arms, short legs, and no tail. The surface of the body is mostly covered with black long hair, but the face, ears, fingers, and toes are exposed and hairless, mainly distributed in central and western Africa. They inhabit tropical rainforests and moist savannas, living in clusters of more than 2-20 individuals per group, led by one adult male. They have a large appetite and enjoy eating fruits, leaves, roots, flowers, seeds, and bark, while some individuals often eat smaller animals. It is rare to live beyond 40 years old in the wild, but in captivity, one can live to over 60 years old.
